Abstract
Primary and secondary masses of heavy reaction products have been
deduced from kinematics and E-ToF measurements, respectively, for the
direct and reverse collisions of
93Nb and 116Sn at 25 AMeV.
Light charged particles have also been measured in coincidence with
the heavy fragments.
Direct experimental evidence of the correlation of energy-sharing with
net mass transfer has been found using information from both the
heavy fragments and the light charged particles.
The ratio of hydrogen and helium multiplicities points to a further
correlation of angular momentum sharing with net mass transfer.
